NOTICE:

Do not keep a motor relay on for more than 5 seconds. When operating it consecutively, wait 20 seconds between each operation.

1. Turn the motor relay on and check the actuator motor operation noise.
   

2. Turn the motor relay off.
   

3. Fully depress the brake pedal and hold it for approximately 15 seconds. Check that the pedal's initial depth is maintained for the entire 15 seconds.
   

4. Turn the motor relay on and check that the pedal does not pulsate.
   

5. Turn the motor relay off and release the pedal.
